GTRN Publication Attribute Fields
The following table lists all attribute fields found in all both of the GTRN Publication datasets in
alphabetical order. The GTRN Publication dataset consists of two feature classes: roads and trails.
The GTRN closure device feature class was migrated to the Structures database. Road and trail
closure devices are indicated in the Structures feature class by BENEFIT (or BENEFIT2) =
‘Road Access Restriction’ with a STRCT_PT_TYPE of Gate, Road Barrier, or Sign.
STRCT_MAT provides the physical material of the road closure or blockage.

GTRN Publication Fields and Attributes Defined
Field and attribute descriptions for GTRN Publication line and point features.
1. Access Rights – AccessRghts
Published in Roads
The access rights field captures which roads public access is secured and which roads the
BLM has the legal administrative right to use on a road segment by road segment
basis.
This field must be used in tandem with the Access Rights Continuity field.
This field does not define physical access. Physical access is determined through a
combination of Access Rights, Access Rights Continuity, and Closure Status.

UNKNOWN
dom_GTRN_acc_rgts
Description
Public access (including BLM) is secured
BLM administrative rights; no public access is secured
No public or BLM access is allowed
Unknown (Default)
This field is independent of management decisions made by the BLM and is a reflection
of exclusive and non-exclusive easements and reciprocal right-of-way agreements. The
access rights values in this field should not be in conflict with the access rights values
identified in the ESMTROW dataset. In instances where the ESMTROW dataset has
more than one access right value the most inclusive value should be used in GTRN, i.e.,
if the BLM has an exclusive easement (public access is secured) with a private landowner
and a non-exclusive (admin access rights) with a timber industry entity on that same road
segment then GTRN should display the public, or most inclusive, access rights.
More GTRN road segments may have the access rights identified than are identified in
the ESMTROW dataset as BLM roads on BLM lands do not require an easement; BLM
roads on BLM lands will always have public access rights. Even though BLM roads on
BLM lands will always have public access rights, as a result of the checkerboard land
pattern the public’s access to those roads may be restricted. It is therefore necessary to
assess the AccessRightsContinuity field.
The ESMTROW data layer includes additional information about the easement or rightof-way, e.g., case number, the authorized use, and the type of feature. It is important to
include the access rights information in both data layers.

2. Access Rights Continuity – AccessRghtsContinuity
Published in Roads
The access rights continuity field captures which roads public access is secured and
which roads the BLM has the legal administrative right to use in the context of the road
network.
This field must be used in tandem with the Access Rights field.
This field does not define physical access. Physical access is determined through a
combination of Access Rights, Access Rights Continuity, and Closure Status.

Description
Continuous public access (including BLM) is secured
BLM administrative rights; no continuous public access is secured
No public or BLM access is allowed
Unknown (Default)
Public access rights are most typically interrupted by use rights secured thru Reciprocal
Right-of-Way Agreements (RROW’s), or any other non-exclusive easement. All BLM
roads tributary to roads without secured public access also do not have secured public
access.
As an example, the BLM-administered land in western Oregon is predominantly
intermingled in a checkerboard pattern with private land. Intermingled private lands are
owned primarily by timber companies and are managed for commercial timber
production. Legal access to federal and private timberlands is provided through longterm or perpetual RROW’s between the United States and private timberland owners as
authorized by the Federal Land and Policy Management Act of 1976 (FLPMA) and other
Federal regulations. A RROW provides both the United States and the private landowner
with a non-exclusive right to use, construct and maintain logging roads on each other’s
property for forest management and removal of forest products. These RROW’s do not
July 7, 2014
Page 6
OR/WA BLM Ground Transportation Publication Data Dictionary
grant rights for public access and recreational use of roads constructed under these
agreements.
BLM typically negotiates exclusive easements with private landowners to obtain access
for forest management activities when a reciprocal agreement is not needed. Unlike
RROW’s, exclusive road easements typically do grant rights for public use.
This attribute has several useful applications: 1) Travel and Transportation Management
(TTM) planning, determining which BLM roads have continuous public access rights and
are therefore “open to public travel” is a critical first step in the TTM planning process.
2) Allocation, this is the setting apart or segregation of a portion of the road replacement
cost, capital expenditure, or road maintenance fees attributable to road uses other than log
hauling (e.g. recreation and other public uses). The net effect of allocation is that RROW
permittees are not required to share in road costs which are not directly attributable to
hauling of timber and other forest products. 3) Federal Land Highway Program (FLHP)
road nominations, all roads nominated for inclusion in this FHWA program must be
“open to public travel”, i.e., have continuous public access rights.

3. Accuracy Feet – AccuracyFt
Published in Roads and Trails
How close, in feet, the spatial GIS depiction is to the actual location on the ground.
There are several factors to consider in GIS error: scale and accuracy of map-based
sources, accuracy of GPS equipment, and the skill level of the data manipulators. A
value of “0” indicates no entry was made. This is the correct value when the
COORD_SRC is another GIS theme (DLG, GCD), Digital Elevation Model (DEM))
because the accuracy is determined by that theme. However, if COORD_SRC is MAP
(digitized from a paper map) or GPS, a value of “0” indicates a missing value that should
be filled in either with a non-zero number or “-1.” A value of “-1” indicates that the
accuracy is unknown and no reliable estimate can be made.

4. Average Route Segment Width – AvgWidth
Published in Roads and Trails
This field is a record of the average width, i.e., the surface width, of a route, measured in
feet. Historically western Oregon captured subgrade width in this field. As Road
Condition Assessments (RCA) were completed the discrepancy in width definitions
became apparent and a new Subgrade Width field was created in FAMS. Until the RCAs
are 100% complete some western Oregon Average Width values in FAMS contain
Subgrade Width. Therefore, in GTRN, for inventoried roads (populated via FAMS) this
is only populated for eastside districts.
5. Segment Beginning Milepost – BeginMilePost
Published in Roads and Trails
The milepost value for the segment origin.
6. Administrative Unit Organization Code – BLMOrgCode
Published in Roads and Trails
A combination of the BLM administrative state and field office which has administrative
responsibility for the spatial entity. This includes which office covers the entity for
planning purposes and which office is the lead for GIS edits. Another agency or
individual may have the physical management responsibility for the on-the-ground entity.
This field applies particularly when a spatial entity crosses resource area or district
boundaries and the administrative responsibility is assigned to one or the other rather than
splitting the spatial unit. Similarly, OR/WA BLM may have administrative responsibility
over some area that is physically located in Nevada, Idaho, and California and vice
versa. When appropriate, the office can be identified only to the district or even the state
level rather than to the resource area level.

7. BLM Road Number - BLMRdNum
Published in Roads
This field contains the BLM road number.
This field is used to populate RoadNum where OwnerDesg = ‘BLM’ and where InvCat =
‘BLM’ AND OwnerDesg = ‘PVT’.
In western Oregon FAMS routes consist of four elements based on where a route starts:
township, range, section, and segment number. The FAMS data entry convention
includes leading zeros and township-range direction. RoadNum is the cartographic
labeling representation of the FAMS field RouteNum for inventoried routes, i.e., no
leading zeros and include the township-range direction only when it’s north or east. The
first three elements – township, range, and section – are separated by dashes (-) rather
than spaces.
The fourth route number element, segment numbers (an alpha-numeric value), should be
stored in the RouteSeg field and not the Rt_Num1 field.

Spokane: 6000, 6700, 6800, 6900, 7000, 7800, 7900, 8800, 8900, and 9800
Vale: 6300, 6600, 7300, 7600, 8300, and 8600
Spurs will be numbered with a 2 digit alpha-numeric system, with a zero used rather than
a blank space for the sake of clarity.
8. BLM Trail Number – BLMTrlNum
Published in Trails
This field contains the BLM trail number.
This field is used to populate TrailNum where OwnerDesg = ‘BLM’ and where InvCat =
‘BLM’ AND OwnerDesg = ‘PVT’.
9. Capital Improvements – CapitalImp
Published in Roads and Trails
The capital improvement field identifies the agency or entity that made a capital
improvement to a road if this agency or entity is different than the road owner. Capital
improvement does not change road ownership. Capital improvements include work and
materials expended to better a road by increasing its construction standard when
compared to its original construction standard. Examples of capital improvements
include: widening and/or surfacing the roadway, adding drainage structures, and
replacing bridges.

12. Closure Status (current) – ClosureStat
Published in Roads and Trails
July 7, 2014
Page 11
OR/WA BLM Ground Transportation Publication Data Dictionary
The Closure Status field represents BLM management decisions. BLM interdisciplinary
teams make determinations about route closures based on impacts to resources and
resource protection. These decisions are based on RMP management direction and are
implemented during an EA, an EIS, or a Travel Management Plan.
The Closure Status field also represents closure restraints placed on routes through
Executive Orders, Legislative Decisions, and court orders. These limitations are outside
of the BLM decision space and typically include prohibited vehicular traffic within
wilderness or areas of critical environmental concern.
BLM management decisions are confined by realty instruments on a route, e.g.,
easements, right-of-ways, and reciprocal right-of-ways. Restrictions placed on a route via
a realty instrument can be found in the Access Rights and Access Rights Continuity
fields.
This field does not define legal or physical access. Legal access is determined through a
combination of the Access and Access Rights Continuity fields. Physical access is
determined through a combination of the Drivability field and closure devices. The
Access Rights and Access Rights Continuity fields, which identify the roads for which
public access is secured, and the Drivability field, a description of the physical drivability
of a route, are independent of the Closure Status field. Refer to the OR/WA BLM
Structures dataset to determine the location of route closure devices, e.g., gates.
This field does not capture short term closure information. This information is captured
with a spatial overlay with the defining closure polygon data. Fire, landslides, and eagle
nesting are examples of short term closure situations.

Open Yearlong (OP) - Currently operated and maintained with no use limitations
enforced by a closure device or regulation other than restrictions based on size, weight, or
class of registration. Routes may not have secured continuous public access rights (see
Access Rights Continuity). Segments may be closed during extreme weather or
emergency conditions. Open yearlong segments will be placed in FAMS operating status.
This domain value applies to BLM owned and non-BLM owned routes.
Open Seasonally (SC) - Currently operated and maintained with a seasonal public and
commercial use limitation enforced by a closure device. The seasonal use limitation does
not apply to administrative use by BLM and/or its permittees. Seasonally open segments
will be placed in FAMS operating status.
This domain value applies only to BLM owned routes.

a gate or sign. In eastern Oregon and Washington this limitation is usually not enforced
by a closure device. The restricted yearlong limitation can be the result of a realty
instrument or the result of a BLM management decision based on an interdisciplinary
team recommendation. The yearlong use limitation does not apply to BLM and/or its
permittees. Restricted yearlong segments will be placed in FAMS operating status.
This domain value applies only to BLM owned routes.
Closed (CL) (Legislated) - Routes closed as a result of an Executive Order, Legislative
Decision, or court order. Vehicle use is prohibited except with the approval of an
authorized officer. Use a different code if the closure status was determined as a result of
a BLM management decision based on an interdisciplinary team recommendation.
Closed roads within wilderness should be removed from FAMS and moved to a NonInv
dataset unless a BLM management decision changes a closed road to a trail. Closed
segments that remain in FAMS will be placed in FAMS storage status.
This domain value applies only to BLM owned routes.
Decommission (long-term) (DR) - Not currently operated and maintained based either
on resource protection needs or maintenance needs as determined through an
interdisciplinary process. Closed, with an earthen barrier or its equivalent, to motorized
vehicles for an extended/indefinite period, but will be operated and maintained again in
the future. Prior to closure will be left in an erosion-resistant condition by establishing
cross drains, eliminating diversion potential at stream channels, and stabilizing or
removing fills on unstable areas. Exposed soils will be treated to reduce sediment
delivery to streams. This closure status category includes segments that have been or will
be closed due to a natural process (abandonment). Decommissioned segments will be
placed in FAMS storage status.
This domain value applies only to BLM owned routes.
Full Decommission (permanent) (FD) - No longer operated and maintained based on an
interdisciplinary process establishing no future need for a segment, e.g., a response to
resource protection and/or lack of use. Use of the route is unauthorized. Closed, usually
with an earthen barrier or its equivalent, to motorized vehicles on a permanent basis; may
be subsoiled (or tilled), seeded, mulched, and planted to reestablish vegetation. Cross
drains, fills in stream channels, and unstable areas will be removed, if necessary, to
restore natural hydrologic flow. Future maintenance will not be required. This closure
status category includes segments that have been or will be closed due to a natural
process (abandonment) and where hydrologic flow has been naturally restored. Fully
decommissioned segments will be placed in FAMS decommission status.
This domain value applies only to BLM owned routes.
Obliteration (full site restoration/permanent) (OB) - No longer operated and
maintained based on an interdisciplinary process establishing no future need for a
segment. Closed, usually with an earthen barrier or its equivalent, to motorized vehicles
on a permanent basis; all drainage structures will be removed. Fill material used in the
original construction will be excavated and placed on the subgrade in an attempt to

reestablish the original ground line. Exposed soil will be vegetated with native trees or
other native vegetation. Obliterated segments will be placed in FAMS decommission
status. Closure by obliteration is rarely used.
This domain value applies only to BLM owned routes.
Other Closed (OC) - Roads or trails that are closed for public use for at least a portion of
the year. These routes may be closed seasonally or year-round. These routes are outside
of the scope of BLM management decisions and as such the BLM definitions don’t
apply. The route owner should be consulted for the road or trail term of use on these
routes.
This domain value applies only to non-BLM owned routes.
Data Clean-up (DC) - Applies to segments moved to the FAMS 'decommission' status
because they were either invalid, duplicate, or erroneous. These segments are excluded
from the nightly FAMS tables.
This domain value applies to BLM owned and non-BLM owned routes.

Passable – 2wd Low Clearance Passenger Vehicle: Roads passable by a 2wd vehicle
designed to carry passengers on improved roads.Passable – Moderate Terrain Vehicle
(eastern Oregon and Washington): Roads that are not passable by all classes of 2wd vehicles
but do not require a 4wd high clearance vehicle. Roads in this category typically have a rough
or uneven surface and/or have had a narrowing in the road width. High clearance 2wd
vehicles such as a standard pickup truck and 4wd sport utility vehicles with low gearing
otherwise designed for rough roads are included in this category. Roads in western Oregon
may exhibit these characteristics; however, the relatively short duration before a deteriorating
western Oregon road becomes impassable or passable only to high clearance vehicles makes
data maintenance at this gradation impractical.
Passable – 4wd High Clearance Vehicle: Roads passable only by high clearance 4wd
vehicles.
Impassable – Roads impassable to all vehicle types as a result of road deterioration or
vegetation overgrowth; project-level road maintenance is required to make these roads
passable. Road deterioration or vegetation overgrowth may be a result of neglect, irregular
maintenance, or management decisions. Roads with a ‘Closure Status’ of decommissioned

24. Federal Land Highway Program - FLHP
Published in Roads
The Federal Lands Transportation Program (FLTP), established under the Moving Ahead
for Progress in the 21st Century Act (MAP-21), Public Law 112-141, is administered by
the USDOT Federal Highway Administration's (FHWA) Office of Federal Lands
Highway in coordination with its core partners: National Park Service, Bureau of Indian
Affairs, US Fish and Wildlife Service, Forest Service, Bureau of Land Management, and
US Army Corps of Engineers. The FLTP funds projects that improve access within the
Federal estate on transportation facilities in the national Federal Lands transportation
facility inventory owned and maintained by the Federal government.
A Federal lands transportation facility (FLTF) is defined as a public highway, road,
bridge, trail, or transit system that is located on, is adjacent to, or provides access to
Federal lands for which title and maintenance responsibility is vested in the Federal
Government, and that appears on the national FLTF inventory. The inventory includes
July 7, 2014
Page 20
OR/WA BLM Ground Transportation Publication Data Dictionary
transportation facilities owned and maintained by a Federal Land Management Agency
(FLMA) that provides access to high-use Federal recreation sites or Federal economic
generators as determined by the FLMA.
BLM’s current definitions of “high use Federal recreation sites” and “high use
Federal economic generators” are based on the Bureau’s existing planning and
management guidance and summarized below.
• High Use Recreation Sites – High Use Recreation Sites generally include those areas
that have been identified as a Recreation Management Area in a land use plan. NLCS
locations, as well as those recreation destinations with significant volume are generally
consistent with the High Use designation. Roads that provide primary or sole access to
the NLCS locations as well as those to heavily utilized Recreation Management Areas
constitute the subset supporting the BLM”s high use recreation sites.
• Federal Economic Generators – These are public lands that provide significant revenue
generation through energy development, timber, or grazing uses as well as high volume
recreation use constitute the BLM’s economic generators. Roads that provide primary or
sole access to economic development are the principle means of “leveraging” the
economic opportunity within the Nation’s public lands. Federal economic generator roads
typically include roads providing access to mineral and renewable energy development,
timber and grazing activities, and high volume recreation locations.

Roads
Level 1 - This level is assigned to roads where minimum maintenance is required to
protect adjacent lands and resource values. These roads are no longer needed and are
closed to traffic. The objective is to remove these roads from the transportation system.
Level 2 - This level is assigned to roads where the management objectives require the
road to be opened for limited administrative traffic. Typically, these roads are passable
by high clearance vehicles.
Level 3 - This level is assigned to roads where management objectives require the road to
be open seasonally or year-round for commercial, recreation, or administrative access.
Typically these roads are natural or aggregate surfaced, but may include low use
bituminous surfaced roads. These roads have a defined cross section with drainage
structures (e.g., rolling dips, culverts, or ditches). These roads may be negotiated by
passenger cars traveling at prudent speeds. User comfort and convenience are not
considered a high priority.
Level 4 - This level is assigned to roads where management objectives require the road to
be open all year (except may be closed or have limited access due to snow conditions)
and which connect major administrative features (e.g. recreation sites, local road systems,

administrative sites, etc.) to County, State, or Federal roads. Typically these roads are
single or double lane, aggregate or bituminous surface, with a higher volume of
commercial and recreational traffic than administrative traffic.
Level 5 - This level is assigned to roads where management objectives require the road to
be open all year and are the highest traffic volume roads of the transportation system.
Trails
Level 1 - These trails are closed to motorized and non-motorized use. This level is the
minimum maintenance required protecting adjacent lands and resource values. The
objective is to remove these trails from the trail system.
Level 2 - Low use trail with little or no contact between parties. There is little or no
monitoring or management of visitor use. Visitors may encounter obstructions like brush
and deadfall.
Level 3 - Moderate use trail with visitor use on a seasonal and/or peak use period with
frequent contact between parties. Trail management is conducted with occasional
monitoring or management of visitor use. Visitors are not likely to encounter
obstructions.
Level 4 - High use trail used during specific times of the year with high frequencies of
contact between parties. These trails have regularly scheduled monitoring or
management of visitor use.
Level 5 - A special high use trail with routine monitoring or management of visitor use.

35. Jurisdiction – Ownership
Published in Roads and Trails
The ownership (juris) field represents the entity that has the authority to set terms of road
maintenance and conditions of road use. Land ownership does not necessarily mean
the road is owned by the same entity. Similarly, road ownership does not necessarily
mean the road is controlled by the same entity.

still hold an active permit.
General Note: Any traffic regulations established by either the U.S. or permittee must be
applicable to all users of the road, including the road owner.
36. Road Functional Classification – RoadClass
Published in Roads
Functional classification, which is the grouping of roads by the character of service they
provide, establishes a systematic approach to road planning, design, and maintenance.
Stratifying the Bureau’s road network by functional classes provides a rational and costeffective basis for (1) the selection and application of geometric design criteria and standards
(e.g., maximum road grades, roadway width, and design speed); and (2) the assignment of
appropriate road maintenance intensity levels (i.e., from basic custodial care to annual
scheduled and preventative maintenance programs).
Most rural highway travel involves movement through networks of roads that can be
described using a functional system based on traffic volume, vehicle speed, trip distance,
travel mobility, and property access. The system of functional classifications in descending
order consists of arterial (for main traffic movement), collector, local (for land access) and
resource roads. The functional classification system helps determine how travel movement
can be channelized through the network in a logical and efficient manner. Each element of
the functional system can serve as a collecting facility for the next highest element.
This functional classification system is more fully described in the Federal Highway
Administration (FHWA) publication Highway Functional Classification: Concepts,
Criteria, and Procedures (Revised 1989). The Bureau has added resource roads to the
system identified in this FHWA plan to better account for the unique function of many
Bureau roads in providing very small-scale public land access. These resource roads
typically carry extremely low traffic volume and accommodate only one or two types of
resource management (see BLM manual 9113).

Arterial Roads (for non-inventoried roads only) – The rural arterial system consists of a
network of roads with the following service characteristics:
a. Linkage of cities, larger towns, and other traffic generators (such as major resort
areas) capable of attracting travel over long distances.
b. Integrated interstate and inter-county service.
c. Internal spacing consistent with population density, so that all developed areas of the
State are within a reasonable distance of arterial highways.
July 7, 2014
Page 27
OR/WA BLM Ground Transportation Publication Data Dictionary
d. Trip lengths and travel densities greater than those predominantly served by rural
collector, local, and resource systems.
e. Design standards provide for high travel speeds and minimum interference to through
movement.
As Bureau roads are predominantly low volume and are generally extensions of or
connectors to State Highway and rural County Road systems, an arterial classification does
not apply normally to Bureau roads (see BLM manual 9113). In fact, in western Oregon
BLM manages no arterial roads.
Collector Roads – The rural collector system generally serves travel primarily of intracounty rather than statewide distances and constitutes those roads on which predominant
travel distance and speed are less than on arterial routes. These roads serve larger towns;
important agricultural areas (e.g. forest management areas); county, state, and federal parks;
and other traffic generators of equivalent intra-county importance. These roads link to the
arterial system and are spaced at intervals consistent with population density to
accommodate traffic from local roads and bring all developed areas within reasonable
distances of collector roads.
Designation of Bureau collector roads is based on the following criteria:
a. Roads that normally provide access to large blocks of public land and connect with
state and county road systems.
b. Roads that accommodate multiple uses and generally receive the highest volume of
traffic of all roads in the Bureau road system.
c. Roads designed to the Bureau’s highest standards may be double lane.
d. Roads designated as scenic routes or Back Country Byways (Type I, see BLM
Handbook H-8357-1).
e. Roads that provide access to recreational areas containing a number of developed
sites and facilities.
f. Roads that provide the most extensive linkage to the local road system.
g. Only roads mapped by ODOT as collectors in accordance with their “Guidelines for
Updating Federal-Aid Urban Boundary and Functional Classification” document
dated July 2003 will be mapped by BLM as collectors. ODOT functional
classification maps can be found at the following website:
http://egov.oregon.gov/ODOT/TD/TDATA/gis/CountyMaps.shtml
Local Roads – The rural local system primarily provides access to lands adjacent to the
collector network and serves travel over relatively short distances. Designation of Bureau
local roads is based on the following criteria:
a.
b.
c.
d.
e.
July 7, 2014
Roads that normally serve smaller areas than collectors and connect with collectors
or state and county road systems.
Roads that accommodate fewer uses and receive lower traffic volumes than
collectors.
Roads designed typically to a single lane width with steeper grades, sharper
horizontal curves, and lower design speeds than collector roads due to
mountainous terrain.
Roads that provide access to small recreational sites, trailheads, special sites and
facilities (i.e., communication sites).
Roads that provide the most extensive linkage to the resource road system and are
spaced at appropriate intervals to collect traffic from resource roads and provide

for public land areas to be within a reasonable distance of a local road. This
eliminates multiple parallel roads.
All local roads tie together arterial, collector, and/or other local roads; no dead-end
roads.
• Exception
Dead-end local roads must access, (1) developed recreation/administrative
sites, BLM quarries, or fire program improvements (e.g., waterholes) or (2) a
minimum of 5 sections (3,200 acres) regardless of the number of tributary
spurs or the length of the road.
Not every road tributary to a collector road needs to be a local road.
Not every linking road needs to be a local road.
Typically, the local network mileage will be 2-4 times the collector network
mileage. This is a reasonableness check, not a hard and fast rule, based on
AASHTO classification study data collected in many states which show there is
considerable consistency in the relative extents of the functional class systems.
Resource Roads - The Bureau resource road system provides access to the remaining
portion of the public lands not accessed by collector or local roads. Designation of Bureau
resource roads is based on the following criteria:
a. Roads that provide point access to public lands and connect with local or collector
roads.
b. Roads are typically for only one or two types of resource management and carry
very low traffic volumes. Typically they are low standard, single lane, natural or
aggregate surfaced logging spurs.
c. Location and design of these roads are governed by safety standards, environmental
compatibility and minimal construction and maintenance costs, and with minimal
consideration for user cost, comfort, or travel time.
d. Roads have no established or designated recreational use (e.g., comfort station,
trailhead, wayside) to attract the public.

39. Road Primary Number – RoadNum
Published in Roads
The intent of this field is to hold the road number of the primary route owner. The
route number placed in this field should be consistent with the agency in the Ownership
Designation field.
RoadNum is derived from BLM_Rd_No, USFS_Rd_No, County_Rd_No, and
Other_Rd_No based on the road owner in the OwnerDesg field. RoadNum will be
populated with the BLMRdNum for privately owned roads where inventory category =
‘BLM’.
This field is used for cartographic labeling and needs to be formatted to allow for map
labels.
Data Population Ruleset
1. If the only road number field populated does not match the road owner then
RoadNum will be left blank and RoadNum2 will be populated.
2. If the road owner is not known and only one of the four orsoedit number fields is
populated then RoadNum will be populated with the sole attributed value.
3. If the road owner is not known and more than one of the four orsoedit number
fields is populated then RoadNum will be populated based on an agreement in
the orsoedit field and the majority underlying land owner. That is:
a. If the BLM_Rd_No field is populated and the underlying land owner, or
land owner majority, is BLM, then RoadNum will be populated with the
BLM_Rd_No field.
b. If the USFS_Rd_No field is populated and the underlying land owner, or
land owner majority, is FS, then RoadNum will be populated with the
USFS_Rd_No field.
c. If the County_Rd_No field is populated and the underlying land owner,
or land owner majority, is private, then RoadNum will be populated with
the Count_Rd_No field.
4. If the road owner is not known and more than one of the four orsoedit number
fields is populated and the populated road number field does not correspond with
the underlying land owner, then RoadNum and RoadNum2 will not be populated
in GTRN pub.

Published in Roads
The intent of this field is to hold any secondary route numbers. These secondary numbers
can either be a second number assigned by the primary road owner or the number
assigned by an agency other than the primary road owner.
RoadNum2 is derived from a secondary number in BLM_Rd_No, USFS_Rd_No,
County_Rd_No, and Other_Rd_No once RoadNum has been populated.
The route number placed in this field does not necessarily need to be consistent with
the agency in the ownership designation field.
This field is used for cartographic labeling and needs to be formatted to allow for map
labels.
41. Route Identifier – RouteID
Published in Roads and Trails
Provides the full BLM route and segment number. This field can be used for cartographic
labeling or as a relate key to other datasets or tables. In western Oregon RouteID is:
RouteNum (rt_num) + RouteSeg (o_csegs). In eastern Oregon RouteID is: RouteNum
(rt_num) + RouteSpur (rte_spur) + BeginMilePost (begml). RouteSeg (o_csegs) and
RouteSpur (rte_spur) do not exist in the trails feature class and therefore are not included
in the Route_ID equation for trails.
42. Route Number – RouteNum

national designation.
BLM Back Country Byway: Back Country Byways are designated through a resource
management plan (RMP) and showcase the variety of richness of BLM's off-the-beaten
track public lands. Most of the byways are either paved or graded gravel and dirt roads,
passable in ordinary passenger cars. Others are safely driven only in a high-clearance
truck or 4-wheel drive vehicle.
National Forest Scenic Byway: The Chief of the Forest Service administratively
designates National Forest Scenic Byways. These routes represent the best of the roads
running through the national forests and showcase outstanding national forest and
grassland scenery.
State Scenic Byway (OR): Oregon State Scenic Byways are designated by the Oregon
Transportation Commission. They have high national or statewide appeal, feature
historic, recreational, archeological, cultural, or natural appeal in addition to scenic
qualities, are a minimum of 30 miles long, and must be passable by passenger car.
State Tour Route (OR): Oregon State Tour Routes are designated by the Oregon
Transportation Commission. They have high local or regional appeal, feature similar
qualities as State Scenic Byways, are a minimum of 20 miles long, and must be passable
by passenger car or four-wheel drive vehicle.
State Scenic and Recreational Highway (WA): Washington State Scenic and
Recreation Highways are designated by the state legislative statute for the purpose of
ensuring the state's most spectacular and diverse landscapes, including scenic, natural,
recreational, cultural, and historic resources.
State Scenic Bikeway (OR): Oregon State Scenic Bikeways are designated by the
Oregon Recreation and Parks Commission. Bikeways are signed bike routes on roads
and bicycle paths that provide access to national, state, or regional resources of
superlative quality and scenic splendor. They can be linear routes a minimum of 40 miles
long, or a loop a minimum of 5 miles long.
Auto Tour Route: These routes are usually self-designated by a variety of entities
including counties, state tourism offices, local chambers of commerce, regional industry
groups, and land management agencies. They usually highlight and market a local or
regional characteristic or product such as a collection of covered bridges, waterfalls,
wineries, farm stands, etc. A subset of auto tour routes focuses specifically on wildlife
viewing opportunities, including the OR and WA Birding Trails.
National Scenic Trail: Part of the congressionally designated National Trail System,
these trails comprise of continuous protected scenic corridors for outdoor recreation.

National Historic Trail: Part of the congressionally designated National Trail System,
these trails recognize broad facets of history such as prominent past routes of exploration,
migration, trade, communication, and military action. Historic trails generally consist of
remnant sites and trail sections, and thus are not necessarily continuous.
National Recreation Trail: Part of the congressionally designated National Trail
System, these trails are recognized by the Federal Government as contributing to the
National Trail System. They vary in length, terrain, difficulty, and accessibility.

Natural Improved: A natural on-site surface that has been improved by being graded
without drainage features or graded and drained with either an inslope, outslope, or
crowned cross section. Drainage features could also include, but are not limited to, side
ditches, lead-off ditches, cross drain culverts, and drain dips/water bars.
Natural Unimproved: A natural on-site surface without grading or drainage features.
No assumption is made about whether a natural unimproved road or trail was originally
constructed or user-created.

55. Trail Primary Number – TrailNum
Published in Trails
The intent of this field is to hold the trail number of the primary route owner. The
route number placed in this field should be consistent with the agency in the Ownership
Designation field.
TrailNum is derived from BLM_Trl_No, USFS_Trl_No, and Other_Trl_No based on the
trail owner in the OwnerDesg field. TrailNum will be populated with the BLMTrlNum
for privately owned roads where inventory category = ‘BLM’.
Reference RoadNum for the specifics on how TrailNum and TrailNum2 are populated.
This field is used for cartographic labeling and needs to be formatted to allow for map
labels.

56. Trail Secondary Number – TrailNum2
Published in Trails
The intent of this field is to hold any secondary route numbers. These secondary numbers
can either be a second number assigned by the primary trail owner or the number
assigned by an agency other than the primary trail owner.
TrailNum2 is derived from BLM_Trl_No, USFS_Trl_No, and Other_Trl_No once
TrailNum has been populated.
The route number placed in this field does not necessarily need to be consistent with
the agency in the ownership designation field.
This field is used for cartographic labeling and needs to be formatted to allow for map
labels.
57. Trail On Road – TrailOnRoad
Published in Trails
This field indicates when a trail is coincident with a road. This information can be used in
combination with the Trail Use field to identify when a trail has shared use with
motorized and non-motorized conveyances. This field does not provide any information
about the road.

61. U.S. Forest Service Road Number – USFSRdNum
Published in Roads and Trails
This field contains the current FS road number. Values should be a 7-digit number with
no text and no punctuation, e.g., 2231714.
The first four digits (2231) represent a Forest Service primary road; the last three digits
(714) represent a Forest Service secondary road. For this example, the following number
scheme would apply:
Line Segment
USFSRdNum Format
FS Arterial
FS Collector
FS Local
2200000
2231000
2231714
RoadNum and
RoadNum2 Format

2231
714
This field is used to populate RoadNum where OwnerDesg = ‘FS’. The 7-digit number is
condensed to 2-, 4-, or 3-digits in the RoadNum field for a more label friendly format.

63. Wilderness Study Area Ways – WSA_Ways
Published in Roads and Trails
WSA_Way Description: A route segment identified and mapped as a “way” at the time a
WSA was officially designated under FLPMA, Section 603, or under FLPMA, Section
202, prior to April 14, 2003 (as per Instruction Memorandum No. 2003-274
implementing the Utah Wilderness Settlement Agreement). The term “way” derives
from BLM’s “roadless” definition in its 1978 Wilderness Inventory Handbook and its
Interim Management Policy Handbook (H-8550-1), which state that “a way maintained
solely by the passage of vehicles does not constitute a road.” The official inventory maps
are held in local BLM District Offices and may contain scale or other mapping errors that
have been corrected in GIS as data sources have improved. This attribute applies only to
those ways, identified during the inventories leading to official WSA designation, where
sufficient on-the-ground evidence of the route currently remains.
